CAR-TRUCK. i

SPECIFICATION forming part of Letters Patent No. 279,434, dated June 12, 1883.

Application filed April 30, 1883. (No model.) I l To aZZ whom it may concern:

Be it known that I, HORACE REsLEY, a citizen of the United States, residing at Cumberland, in the county of Alleghany and State of Maryland, have invented a new 'and useful Improvement in Car-Trucks, of which the following is a specication.

The object of my invention is to provide simple, inexpensive, but efficient and durable means for preventing accidents to railwaytrains by reason of pivoted car-trucks jumping77 the rails when passing around curves or upon meeting small obstructions, and also for preventing wear and tear of machinery and rails and lessening the power usually required in consequence of impingeinent of the wheels upon the outer rails. y

The invention consists in the construction, arrangement, and operation of parts, as hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a plan view showing a car-truck provided with Iny attachment, a part of the base-frame of the ear being broken away. Fig. 2 is a plan of the same inverted. Fig. 3 is a plan inverted, showing a modification.

Referring to Figs. l and 2, the trucks A are pivoted centrally, in the usual manner, to the body of the car B. To each end of the swinging bolster a, of each truck is attached a flat;

bar, C, which extends forward and is secured at the corner of the car by means of a screwbolt, b, which passes through a slot, c, formed in the broad end of said bar. The slot c is arranged diagonally that is to say, parallel to a line drawn radially from the center or pivot' of the truck A.

In passing around a curve pivoted trucks always change position relatively to the longitudinal center of the car, and, as the outer wheels crowd against the outer rail, their tendency is to cross it or jump the track. This is especially the case in curves having a short radius. By means of the slotted bars C this result is prevented, since they limit the move- Vment of the trucks A on their pivots, or, in other words, allow them to assume only such angles to the longitudinal-center of the car as is compatible with safety. This angle is approximately indicated when the cross-beams or bolster-s a of the truck are at right angles where they act as stops and limit the Inove- Y ment of the' truck.

As a further means for keeping the trucks in proper position on the rails, I employ the V-shaped frame D and link F, which are applied as follows: The bars composing the V- frame are rigidly attached to the swinging bolster a near its ends, and the link is pivoted to the apex of the angle formed by such bars and to a frame or piece of lumber or iron which extends across the base-frame of the car. Thus, when the trucks turn in running curves, the V-frame D and link E will serve to hold them in the limits prescribed by due regard to safety.

In Fig. 3 I show amodication of the slotted bars seen in Figs. 2 and 3.

In this case the stop-bars C are rigidly secured to the truck-bolster a, and have slots formed in their outer ends which are parallel to arcs of a circle described from the pivot of the truck.,

`The operation is obvious.

l. The combination, with the car body and,

truck pivoted thereto, ofthe stop-bars C, which are attached to the truck and have slots in their outer ends to receive bolts or pins fixed in the bottom. ofthe car, as shown and described, for the purpose specified;

2. The combination ofthe slotted bars C, the V-i'rame D, and pivoted link E with the pivoted truck A and car-body B, all said parts being constructed and arranged as shown and described.
